Step 201: sending IDC assistance information to a network-side device,wherein the network-side device includes at least one of an MN and anSN.

Sending the IDC assistance information to the network-side device may besending the IDC assistance information to at least one of the MN and theSN, wherein, the IDC assistance information may be information forassisting at least one of the MN and the SN in configuring assistanceconfiguration information of an IDC interference cancellation. After theMN and/or the SN receives the assistance information, the MN and/or theSN may configure the assistance configuration information of IDCinterference cancellation corresponding to the assistance information.

For example, the IDC assistance information may include at least one oftime-domain assistance information, frequency-domain assistanceinformation, space-domain assistance information, an interfered radiotechnology type, and the like.

Further, the time-domain assistance information includes, but is notlimited to, at least one of following: frequency-domain information inwhich the time-domain assistance information acts, space-domaininformation in which the time-domain assistance information acts,configuration information of downlink discontinuous reception to which auser terminal prefers, bitmap information of downlink reception to whicha user terminal prefers, configuration information of uplinkdiscontinuous transmission to which the user terminal prefers, bitmapinformation of uplink transmission to which a user terminal prefers, andthe like.

The space-domain assistance information includes, but isnot limited to, at least one of following: space-domain identificationinformation of a frequency subject to interference, space-domainidentification information of an interference source, and the like. Thefrequency-domain information or the frequency-domain identificationinformation described above includes, but is not limited to, at leastone of following: a frequency identification, a bandwidth range, abandwidth part (Bandwidth Part, BWP) identifier, a cell identifier, acell group identifier, and the like. The space-domain information or thespace-domain identification information described above includes, but isnot limited to, at least one of following: a beam identifier, a beampair identifier, a Synchronization Signal Block (SSB) identifier, aChannel State Information Reference Signal (CSI-RS) identifier, and aQuasi Co-Location (QCL) identifier. The above-mentioned interfered radiotechnology types include, but are not limited to, at least one offollowing: a 2G technology identifier, a 3G technology identifier, a 4Gtechnology identifier, a 5G technology identifier, and the like.

Step 202: receiving the assistance configuration information of IDCinterference cancellation sent by the network-side device, wherein theassistance configuration information of IDC interference cancellationcorresponds to the IDC assistance information.

Correspondence between the assistance configuration information of IDCinterference cancellation and the IDC assistance information may becorrespondence in which at least one of the MN and the SN configures theassistance configuration information of IDC interference cancellationfor a user terminal according to the IDC assistance information, forexample, the MN or the SN identifies resources (e.g., time-domainresources, frequency-domain resources, or space-domain resources),subject to IDC interference, of a user terminal, or identifies radiotechnology type, subject to IDC interference, or identifies transmissionand reception resources preferred by the user terminal, through the IDCassistance information. The MN or the SN configures correspondingassistance configuration information of IDC interference cancellationfor a user terminal for a purpose of reducing or eliminating the IDCinterference. If uplink transmission or downlink reception of resourcessubject to the IDC interference is used to be stopped, or uplinktransmission or downlink reception of transmission and receptionresources preferred by the user terminal. A configuration process of theassistance configuration information of IDC interference cancellation isnot limited in some embodiments of the present disclosure.

The assistance configuration information of IDC interferencecancellation described above may be assistance configuration informationfor eliminating or reducing IDC interference. Thus, by configuring theassistance configuration information of IDC interference cancellation,the user terminal can reduce or eliminate the IDC interference, therebyimproving reliability and throughput of transmitting and receiving databy the user terminal. For example, the user terminal performs, accordingto the assistance configuration information of IDC interferencecancellation, corresponding interference processing operations such asstopping uplink transmission and/or stopping downlink reception.Further, the assistance configuration information of IDC interferencecancellation may be configuration information of stopping uplinktransmission of a certain resource or configuration information ofstopping downlink reception of a certain resource, or may also beconfiguration information for reducing a transmission power of an uplinktransmission of a certain resource, or may also be the number of uplinktransmission subframes (autonomous Denial sub-frames) allowed to beignored by the user terminal, or a duration of uplink transmission(autonomous Denial Validity) allowed to be ignored by the user terminal,or the like, thereby the user terminal performs a correspondinginterference processing operation to reduce or eliminate IDCinterference. For example, when interference occurs, uplink transmissionmay be ignored within a duration of uplink transmission allowed to beignored by the user terminal, and the number of subframes in which theuplink transmission is ignored is less than or equal to the number ofuplink transmission subframes allowed to be ignored by the UE.

It should be noted that both the IDC assistance information and theassistance configuration information of IDC interference cancellationmay be sent through a control plane signaling, thereby ensuringtransmission performance of the IDC assistance information and theassistance configuration information of IDC interference cancellation.

Through the above steps, the network-side device can configure theassistance configuration information of IDC interference cancellationfor a user terminal, thereby enable the user terminal to reduce oreliminate IDC interference, Further, reliability and throughput oftransmitting and receiving data by the user terminal are improved.

It should be noted that the above method may be applied to a 5G system,but is not limited thereto, for example, it may also be applied to afuture 6G system or the like.

In an embodiment of the present disclosure, the IDC assistanceinformation is sent to a network-side device, wherein, the network-sidedevice includes at least one of an MN and an SN, and assistanceconfiguration information of IDC interference cancellation sent by thenetwork-side device is received, wherein, the assistance configurationinformation of IDC interference cancellation corresponds to the IDCassistance information. Since the user terminal can acquire theassistance configuration information of IDC interference cancellationsent by the network-side device, the IDC interference in the userterminal can be reduced.

Referring to FIG. 3, FIG. 3 is a flowchart of another method oftransmitting configuration information provided in some embodiments ofthe present disclosure, and the method is applied to a user terminal, asshown in FIG. 3, the method includes the following steps 301-305.

Step 301: receiving a request message sent by an MN, wherein the requestmessage is used to request the user terminal to report capabilityindication information.

The request message may be sent through an SRB between the user terminaland the MN to request the user terminal to report capability indicationinformation to the MN.

Step 302: sending capability indication information to the MN, whereinthe capability indication information is used to indicate whether theuser terminal supports an IDC assistance function.

After the user terminal receives the request message, the user terminalmay send, to the MN, the capability indication information indicatingwhether the user terminal supports the IDC assistance function, toinform the MN whether the user terminal supports the IDC assistancefunction. The IDC assistance function may be a function capable ofreducing or eliminating IDC interference through the assistanceconfiguration information of IDC interference cancellation.

Step 303: receiving report indication information, wherein the reportindication information is used to indicate whether the user terminal isallowed to report IDC assistance information.

The report indication information may be determined by the MN accordingto the capability indication information or by negotiation between theMN and the SN according to the capability indication information. Inthis way, the user terminal may or may not, through the above-mentionedreport indication information, be allowed to report the IDC assistanceinformation, thereby avoiding the user terminal from directly reportingthe IDC assistance information, which may result in waste oftransmission resources. Thus, an effect of saving transmission resourcesis achieved. For example, in some cases, the network side does not allowthe user terminal to report, and the IDC assistance information reportedin this case may be invalid, thus directly reporting the IDC assistanceinformation by the user terminal is a waste of transmission resources.

As an optional embodiment, if an SRB is not established between the userterminal and the SN, the report indication information is sent by theMN. The report indication information is used to indicate whether atleast one of the Master Cell Group (MCG) and the secondary cell group(SCG) allows the user terminal to report IDC assistance information.

This embodiment may be implemented under a condition that the SRB is notestablished between the user terminal and the SN. Thus, under thecondition that the SRB is not established between the user terminal andthe SN, the MN sends the report indication information to the userterminal, and may indicate whether the MCG allows the user terminal toreport the IDC assistance information, and may also indicate whether theSCG allows the user terminal to report the IDC assistance information.In this way, the user terminal can report accordingly according toinstructions of the MCG and the SCG, so that the network side canconfigure the user terminal to report the IDC assistance informationthrough different SRBs, so as to improve flexibility of the IDCassistance information and accommodate different communication scenariosand service requirements.

In another optional embodiment, if an SRB is established between theuser terminal and the SN, the report indication information includes atleast one of first report indication information and second reportindication information, wherein, the first report indication informationis report indication information sent by the MN for indicating whetherthe MCG allows the user terminal to report the IDC assistanceinformation, and the second report indication information is reportindication information sent by the SN for indicating whether the SCGallows the user terminal to report the IDC assistance information.

This embodiment may be implemented under a condition that an SRB (forexample, SRB3) is established between the user terminal and the SN.Thus, under this condition, the MN sends indication information forindicating whether the MCG allows the user terminal to report the IDCassistance information, and the SN sends indication information forindicating whether the SCG allows the user terminal to report IDCassistance information. Thus, the user terminal can report accordinglyaccording to instructions of the MCG and the SCG.

It should be noted that, in the two optional embodiments, the MN maysend, to the SN before the user terminal receives the report indicationinformation, the capability indication information reported by the userterminal. The configuration information of the IDC assistanceinformation is determined by the MN and the SN through transmissionsignaling, wherein, the configuration information of the IDC assistanceinformation includes at least one of following: a measurement objectidentifier, a measurement configuration identifier, a measurementidentifier, and the report indication information.

The measurement object identifier may be a measurement object foridentifying one or more frequencies, and the measurement configurationidentifier may be configuration for identifying one or more triggeringmeasurements, and the measurement identifier may be an identifier forassociating the measurement object identifier with the measurementconfiguration identifier. The report indication information is used toindicate whether at least one of the MCG and the SCG allows the userterminal to report the IDC assistance information.

In this way, the MN and the SN can negotiate and control theconfiguration information of the IDC assistance information reported bythe user terminal, so as to improve performance of the configurationinformation of the IDC assistance information.

For example, the configuration information of the IDC assistanceinformation is sent by the MN to the SN, and the SN sends or does notsend a feedback message to the MN. The feedback message is used toindicate whether to accept the configuration information of the IDCassistance information, wherein a case that the SN does not send thefeedback message means that the SN accepts the configuration informationof the IDC assistance information. In this way, the MN can send theconfiguration information of the configured IDC assistance informationto the SN for confirmation, and the SN can selectively feedback whetheror not to accept the configuration information, and if the SN does notsend the feedback message, then the SN accepts the configurationinformation.

As another example, the configuration information of the IDC assistanceinformation is sent by the SN to the MN, and the MN sends or does notsend a feedback message to the SN. The feedback message is used toindicate whether to accept the configuration information of the IDCassistance information, wherein a case that the MN does not send thefeedback message means that the MN accepts the configuration informationof the IDC assistance information. In this way, the SN can send theconfiguration information of the configured IDC assistance informationto the MN for confirmation, and the MN can selectively feedback whetheror not to accept the configuration information, and if the MN does notsend the feedback message, then the MN accepts the configurationinformation.

Of course, the configuration information of the IDC assistanceinformation configured by the MN or the SN can also be modified by asignaling between the MN and the SN until both the MN and the SN acceptthe configuration information, so as to improve performance of theconfiguration information of the IDC assistance information.

It should be noted that, in this embodiment, steps 301 to 303 areoptional, and for example, it may also be implemented that the userterminal does not report the capability indication information to theMN.

Step 304: sending the IDC assistance information to a network-sidedevice, wherein the network-side device includes at least one of an MNand an SN.

The IDC assistance information may include at least one of following:time-domain assistance information, frequency-domain assistanceinformation, space-domain assistance information, an interfered radiotechnology type, and the like. The time-domain assistance information,the frequency-domain assistance information, the space-domain assistanceinformation, and the interfered radio technology type may be time-domainassistance information, frequency-domain assistance information,space-domain assistance information and the interfered wirelesstechnology type in a case that the user terminal is subject to the IDCinterference.

Step 305: receiving the assistance configuration information of IDCinterference cancellation sent by a network-side device, wherein theassistance configuration information of IDC interference cancellationcorresponds to the IDC assistance information.

The assistance configuration information of IDC interferencecancellation can be configuration information which enables the userterminal to reduce or eliminate the IDC interference. For example, theassistance configuration information of IDC interference cancellationincludes, but is not limited to, at least one of following: time-domaininformation for stopping uplink transmission, frequency-domaininformation for stopping uplink transmission, space-domain informationfor stopping uplink transmission, an uplink channel type for stoppinguplink transmission, time-domain information for stopping downlinktransmission, frequency-domain information for stopping downlinktransmission, space-domain information for stopping downlinktransmission, and a downlink channel type for stopping downlinktransmission. In this way, the user terminal can perform a correspondinginterference processing operation through the assistance configurationinformation of IDC interference cancellation described above. Forexample, uplink transmission and/or the downlink reception are stoppedon resources corresponding to the assistance configuration informationof IDC interference cancellation, so as to reduce or eliminate the IDCinterference.

As an optional embodiment, the network-side device is the MN, IDCassistance information includes at least one of IDC assistanceinformation of the MCG and IDC assistance information of the SCG. Theassistance configuration information includes at least one of theassistance configuration information of IDC interference cancellation ofthe MCG and the assistance configuration information of IDC interferencecancellation of the SCG.

For example, if an SRB is not established between the user terminal andthe SN, sending IDC assistance information to the network-side devicemay include sending the IDC assistance information to the MN, wherein,the IDC assistance information includes at least one of IDC assistanceinformation of the MCG and IDC assistance information of the SCG.

In addition, the IDC assistance information of the MCG may be IDCassistance information sent by the user terminal to the MCG or the MN,and the IDC assistance information of the SCG may be IDC assistanceinformation sent by the user terminal to the SCG or the SN, and the IDCassistance information of the MCG and the IDC assistance information ofthe SCG may be the same or different assistance information.

Thus, this embodiment may implement a case that the user terminal sendsat least one of the IDC assistance information of the MCG and the IDCassistance information of the SCG to the MN without establishing an SRBbetween the user terminal and the SN.

In addition, in this embodiment, receiving the assistance configurationinformation of IDC interference cancellation sent by the network-sidedevice may include receiving the assistance configuration informationsent by the MN, wherein, the assistance configuration informationincludes at least one of following: the assistance configurationinformation of IDC interference cancellation of the MCG and theassistance configuration information of IDC interference cancellation ofthe SCG.

The assistance configuration information of IDC interferencecancellation of the MCG may correspond to the IDC assistance informationof the MCG, and the assistance configuration information of IDCinterference cancellation of the SCG may correspond to the IDCassistance information of the SCG. Correspondence between the assistanceconfiguration information of IDC interference cancellation of the MCGand the IDC assistance information of the MCG may be the assistanceconfiguration information of IDC interference cancellation configured bythe MN according to the IDC assistance information of the MCG, and whenthe MN configures the configuration information, the MN may also referto the IDC assistance information of the SCG, or the assistanceconfiguration information of IDC interference cancellation of the MCGmay be configured by the SN, which is not limited thereto.Correspondence between the assistance configuration information of IDCinterference cancellation of the SCG and the IDC assistance informationof the SN may be implemented by sending, by the MN to the SN, at leastone of the IDC assistance information of the MCG and the IDC assistanceinformation of the SCG reported by the user terminal, and configuringthe assistance configuration information of IDC interferencecancellation according to the IDC assistance information of the SCG. Ofcourse, when the SN configures the configuration information, the SN mayalso refer to the IDC assistance information of the MCG, or theassistance configuration information of IDC interference cancellation ofthe SCG may be configured by the MN, which is not limited thereto.

For example, the MN sends the IDC assistance information to the SN, andthen the MN receives the assistance configuration information of IDCinterference cancellation of the SCG sent by the SN. Thus, theassistance configuration information of IDC interference cancellationsent by the MN to the user terminal includes at least one of theassistance configuration information of IDC interference cancellation ofthe MCG and the assistance configuration information of IDC interferencecancellation of the SCG.

Through the above steps, it may be implemented that the user terminalobtains at least one of the assistance configuration information of IDCinterference cancellation of the MCG and the assistance configurationinformation of IDC interference cancellation of the SCG through the MNwithout establishing an SRB between the user terminal and the SN,thereby reducing or eliminating IDC interference imposed on at least oneof the MCG and the SCG, or reducing or eliminating IDC interferencegenerated by at least one of the MCG and the SCG.

In addition, in this embodiment, the MN may send the above-describedassistance configuration information to the user terminal through anunused SRB, thereby making full use of SRBs in a communication system.

The network-side device includes at least one ofthe MN and the SN; the assistance configuration information includes atleast one of following: the assistance configuration information of IDCinterference cancellation of the MCG and the assistance configurationinformation of IDC interference cancellation of the SCG.

For example, sending the IDC assistance information to the network-sidedevice may include sending the IDC assistance information of the MCG toat least one of the MN and the SN.

Sending the IDC assistance information of the MCG to the MN may besending the IDC assistance information through SRB0, SRB1, or SRB2between the user terminal and the MN. Sending the IDC assistanceinformation of the SCG to the SN may be sending the IDC assistanceinformation through an SRB3 between the user terminal and the SN toefficiently utilize each SRB.

In this way, in this embodiment, when the SRB is established between theuser terminal and the SN, corresponding IDC assistance information canbe sent to the MN and the SN, respectively. Thus, it is realized thatthe same or different IDC assistance information are reported fordifferent cell groups, and the corresponding assistance configurationinformation of IDC interference cancellation are configured by the MNand the SN.

In addition, in this embodiment, the assistance configurationinformation including at least one of the assistance configurationinformation of IDC interference cancellation of the MCG and theassistance configuration information of IDC interference cancellation ofthe SCG may be understood as: receiving, by the user terminal, theassistance configuration information of IDC interference cancellation ofthe MCG sent by the MN and also receiving, by the user terminal, theassistance configuration information of IDC interference cancellation ofthe SCG sent by the SN; or, receiving, by the user terminal, theassistance configuration information of IDC interference cancellation ofthe MCG sent by the MN, or receiving, by the user terminal, theassistance configuration information of IDC interference cancellation ofthe SCG sent by the SN.

The assistance configuration information of IDC interferencecancellation of the MCG may correspond to the IDC assistance informationof the MCG, and the assistance configuration information of IDCinterference cancellation of the SCG may correspond to the IDCassistance information of the SCG.
